Nuclear Power Plants in Oregon & Washington
Columbia
Location: WA
Operator: Energy Northwest
Configuration: 1 X 1,250 MW BWR
Operation: 1984
Reactor supplier: GE
T/G supplier: WH
EPC: Burns & Roe, Bechtel
Quick facts: Columbia was developed and built as the Washington Public Power Supply System WNP-2 project, and is the only one to complete of the five units originally proposed as part of the WPPSS nuclear program. When initially proposed, the toal cost of all 5 units was expected to be $4.5bn. WNP-2 was built on an 1,089ac site leased from the U.S. Department of Energy's Hanford Reservation on the Columbia River. The site was certified by the state in 1972 and the construction permit was issued in Mar 1973. Commercial operation was in Dec 1984. Electricity is sold at cost to BPA. Energy Northwest is a joint operating agency with 28 member utilities. The unit had its best year ever in 2012 running continuously except for a 10-day maintenance outage in May. Total production was 9.34 TWh.

Hanford N
Location: WA
Operator: Washington Public Power Supply System
Configuration: 1 X 860 MW
Operation: 1966 (ret 1988)
Reactor supplier: n/a
T/G supplier: GE
Quick facts: This was a unique generating unit running off waste heat from a graphite-moderated plutonium production reactor at the U.S. Department of Energy Hanford Reservation on the Columbia River. The project originated in 1956 as the last of nine plutonium production reactors at Hanford.

Trojan
Location: OR
Operator: Portland General Electric
Configuration: 1 X 1,216 MW PWR
Operation: 1976 (ret 1992)
Reactor supplier: WH
T/G supplier: GE
EPC: Bechtel
Quick facts: This was the only nuclear plant in Oregon and is the largest LWR to have been decommissioned. Trojan had many features later incorporated in the Westinghouse Standard Nuclear Unit Power Plant System (SNUPPS), a 4-loop PWR design built at Callaway 1&2 (Unit-2 was cancelled) and Wolf Creek in the USA and, with some modifications, at Sizewell-B in England.

WNP 1 (Hanford)
Location: WA
Operator: Washington Public Power Supply System
Configuration: 1 X 1,340 MW PWR
Operation: n/a (construction stopped 1982)
Reactor supplier: BW
T/G supplier: WH
EPC: United Engineers & Constructors
Quick facts: The WNP 1/4 units were co-located with WNP-2 on an unrestricted portion of the Hanford site. The construction contract for WNP-1 was signed on 6 Feb 1973. WNP-1 construction was stopped in May 1982 at about 65% completion For 12yrs, it was maintained in that condition at a cost of about $5mn/yr. The final termination decision was made in 1994 after intermittent discussion of using the facility as a production reactor. The CP was terminated on 8 Feb 2007.

WNP 3/5 (Satsop)
Location: WA
Operator: Washington Public Power Supply System
Configuration: 2 X 1,324 MW PWR
Operation: n/a (construction terminated 1982)
Reactor supplier: CE
T/G supplier: WH
EPC: Ebasco
Quick facts: The construction contract for WNP-3 was signed on 25 Sep 1973. Construction started in 1977. In Jan 1982, WPPSS stopped construction on WNP-4 at Hanford and WNP-5 at Satsop site as the total cost estimate for all five of the system's planned nuclear units was projected to exceed $24bn. WPPSS later defaulted on $2.25bn in bonds and ongoing litigation slowed funding for the WNP 1 and 3 projects Unit-3 was about 73% complete when construction was suspeneded in Jul 1983. WNP-5 was said to be 16% complete when it was cancelled. WNP 3&5 were among the few U.S. units designed to use 100% MOX cores.

WNP 4 (Hanford)
Location: WA
Operator: Washington Public Power Supply System
Configuration: 1 X 1,340 MW PWR
Operation: n/a (construction stopped 1981)
Reactor supplier: BW
T/G supplier: WH
EPC: United Engineers & Constructors
Quick facts: Unlike WNP 1-3, which were financed with the backing of BPA, WNP 4&5 were directly financed by WPPSS. Construction on the WNP 4&5 units was stopped in May 1981 and officially abandoned on 22 Jan 1982. WNP-4 was said to be 24% complete when it was cancelled.
